Software Engineering Intern (Remote)

More than 9,000 organisations use our HR and payroll suite, from regional hospitals to school districts. Public sector agencies, utilities and large health systems licence our asset management platform under multi-year contracts.

About the role

We need a student who can write clean code, test it and explain what it does. Prior internships are not required. Remote position. Most of the team is in Stockholm, but nobody is required to come in. We talk mostly in Slack and hop on quick calls when something needs discussing.

What you'll do

• Build REST API endpoints and document them in Postman or Swagger
• Add unit tests with pytest or Jest so new code does not lower coverage
• Debug failing builds in the GitHub Actions pipeline and note what caused them
• Refactor old modules when asked, keeping behaviour the same
• Query and update data in PostgreSQL or MySQL, including simple migrations
• Present a short demo of your work to the team every two weeks
• Join the daily 15-minute standup on Google Meet and post a short written update in Slack
• Profile slow endpoints and suggest fixes, such as adding an index or caching a result

Who can apply

• Eligible to work in Sweden
• Currently enrolled in a bachelor's or master's degree, graduating 2026, 2027 or 2028
• Based in Sweden for the duration of the internship
• Available for the full internship period
• Good grasp of at least one programming language: Python, Java, JavaScript or C++
• Own laptop with at least 8 GB RAM and a reliable internet connection
• Comfortable writing simple SQL queries (SELECT, JOIN, GROUP BY)
• Some experience with Git, even if only on college or personal projects
• Basic understanding of data structures, OOP and how HTTP requests work
• A GitHub profile with at least two projects you wrote yourself
